Using GridBagLayout
I have a form with five textfields and five labels that correspond to these textfields. How could I use gridbaglayout to lay them out in this manner:
label1 textfield1
label2 textfield2
...
...
label5 textfield5
button1 button2
-------------------------- ---------- --
Any code examples do help answer this question would be very helpful

Try this:
GridBagLayout m_Bag = new GridBagLayout();
GridBagConstraints m_C = new GridBagConstraints();
protected void addRow(String labelName, int textLength)
{
m_C.anchor = GridBagConstraints.EAST;
m_C.gridwidth = GridBagConstraints.RELATIV E;
Label lab = new Label(labelName);
m_Bag.setConstraints(lab, m_C);
add(lab);
m_C.anchor = GridBagConstraints.WEST;
m_C.gridwidth = GridBagConstraints.REMAIND ER;
TextField txt = new TextField(textLength);
m_Bag.setConstraints(txt, m_C);
add(txt);
}
public void init()
{
setFont(new Font("Helvetica", Font.PLAIN, 14));
setBackground(Color.white) ;
setLayout(m_Bag);
m_C.insets = new Insets(3,5,3,5);
addRow("First Name:", 10);
addRow("Last Name:", 20);
addRow("E-mail:", 30);
}
GridBagLayout m_Bag = new GridBagLayout();
GridBagConstraints m_C = new GridBagConstraints();
protected void addRow(String labelName, int textLength)
{
m_C.anchor = GridBagConstraints.EAST;
m_C.gridwidth = GridBagConstraints.RELATIV
Label lab = new Label(labelName);
m_Bag.setConstraints(lab, m_C);
add(lab);
m_C.anchor = GridBagConstraints.WEST;
m_C.gridwidth = GridBagConstraints.REMAIND
TextField txt = new TextField(textLength);
m_Bag.setConstraints(txt, m_C);
add(txt);
}
public void init()
{
setFont(new Font("Helvetica", Font.PLAIN, 14));
setBackground(Color.white)
setLayout(m_Bag);
m_C.insets = new Insets(3,5,3,5);
addRow("First Name:", 10);
addRow("Last Name:", 20);
addRow("E-mail:", 30);
}

I have also been having trouble lining up the buttons on the bottom. I want them lined up right below the columns. Your code worked great! Thanks for all your help!!! If you have any more code for these buttons that would be a huge help. I just started using Java.
Have you ever used the KeyPressManager control in Visual Cafe Pro for tabbing through components? We tried to use your code with the KeyPressManager but it does not seem to work right. Here is our code:
Any ideas???
import java.awt.*;
import java.applet.*;
import symantec.itools.awt.*;
public class GridBagLayoutTest extends Applet
{
KeyPressManagerPanel tabControl = new KeyPressManagerPanel();
GridBagLayout gridbag = new GridBagLayout();
GridBagConstraints constraints = new GridBagConstraints();
protected void addRow(String labelName, int textLength)
{
constraints.anchor = GridBagConstraints.EAST;
constraints.gridwidth = GridBagConstraints.RELATIV E;
Label lab = new Label(labelName);
gridbag.setConstraints(lab , constraints);
add(lab);
constraints.anchor = GridBagConstraints.WEST;
constraints.gridwidth = GridBagConstraints.REMAIND ER;
TextField txt = new TextField(textLength);
gridbag.setConstraints(txt , constraints);
add(txt);
}
public void init()
{
//{{INIT_CONTROLS
setLayout(null);
addNotify();
resize(430,270);
//}}
setFont(new Font("Helvetica", Font.PLAIN, 14));
setBackground(Color.white) ;
setLayout(gridbag);
constraints.insets = new Insets(3,5,3,5);
addRow("First Name:", 20);
addRow("Last Name:", 20);
addRow("E-mail:", 30);
addRow("Address 1:", 30);
addRow("Address 2:", 30);
addRow("City:", 20);
addRow("Postal Code:", 10);
addRow("PO Box:", 10);
addRow("State:", 20);
addRow("Province:", 20);
addRow("Country:", 20);
addRow("Phone:", 13);
addRow("Fax:", 13);
}
//{{DECLARE_CONTROLS
//}}
}

To add buttons:
m_C.insets = new Insets(10,5,3,5);
m_C.anchor = GridBagConstraints.EAST;
m_C.gridwidth = GridBagConstraints.RELATIV E;
Button but1 = new Button("First");
m_Bag.setConstraints(but1, m_C);
add(but1);
m_C.anchor = GridBagConstraints.WEST;
m_C.gridwidth = GridBagConstraints.REMAIND ER;
Button but2 = new Button("Second");
m_Bag.setConstraints(but2, m_C);
add(but2);
Unfortunately, I don't work with Visual Cafe.
m_C.insets = new Insets(10,5,3,5);
m_C.anchor = GridBagConstraints.EAST;
m_C.gridwidth = GridBagConstraints.RELATIV
Button but1 = new Button("First");
m_Bag.setConstraints(but1,
add(but1);
m_C.anchor = GridBagConstraints.WEST;
m_C.gridwidth = GridBagConstraints.REMAIND
Button but2 = new Button("Second");
m_Bag.setConstraints(but2,
add(but2);
Unfortunately, I don't work with Visual Cafe.
To use KeyPressManagerPanel, most likely you have to use its add() method - check with the docs. If it's true, then in addRow() and for the buttons use tabControl.add() instead of just add().
